Description

Steps to reproduce:
1. Create a Flex 4 application that has a DropDownList
2. Load this application into a SWFLoader with loadForCompatibility=true into a Flex 4 main container SWF
3. When you open the DropDownList, a run-time error is encountered as follows - note UcompOSSWFLoader simply extends SWFLoader, and this issue is occurring with the Halo ComboBox too. Marshalling classes are compiled into both applications.

ReferenceError: Error #1069: Property http://www.adobe.com/2006/flex/mx/internal::computedMatrix not found on com.ucompass.ucompos.controller.factories.extensions.UcompOSSWFLoader and there is no default value.
